have a G13 Pineapple Express growing in soil/perlite with a layer of perlite on top that began developing spots on the lower sets of leaves a week and 2 days ago. This began after feeding a tiny amount of Mega Crop. After noticing the spots I let the soil dry out and watered with 6.3 ph distilled water till run off. I also haven’t watered it for 4-5 days just to make sure it’s not overwatered and dry before watering again. Now the spots are developing on the next set of leaves and the cotyledons and first set of leaves are becoming yellow. I’m also growing a Barney’s Peyote Critical and it seems to be doing great after feeding Mega Crop and looks healthy and overtook the Pineapple in leaf size a few days ago. Thanks for reading this and any help is appreciated. Also, if you need more pictures of the Pineapple I can do that.

just water ph fresh water for the next week or 2 they dont need anything like mega crop for at least another 3-4 weeks give them a light kelp and maybe a light thrive till they muter enough i gather they are in soil ?

Imo you didnt feed it, the deficiency was all ready there and you fed it, the deficiency showed up so that you could see it, blamed it on the nutes then you flushed it back to where it was ...starving for nutes.

no microbes to feed the plant.

I say when you pot up use a lot of work castings and feed something organic that wont harsh the lil thing like store bought nutes..they suck..been giving me hell every time..so much to figure out and test..with those..organic just grows the plant with ease..just a thought tho..I give the same advice on every thread..coconut water and aloe juice diluted..it has been a miracle worker for my current grow..but I'm still a noob so not a lot to compare it to yet..but it takes out the worry with nute schedules

this would be my answer.
All I see in the OP pics are a hungry plant.

I fed both plants the recommended amount for seedlings using the calculator on mega crops site. I use water bottles at the moment instead of a gallon jug to hold the ph corrected distilled water due to the ease and size so the amount of nutes I used was like .14 of a gram which was basically a tiny pinch. The plants are in espoma organic seedling starter mix with 30% perlite. I’m just concerned that it could be root rot since the lower leaves are becoming more yellow each day, crispier and the spots are now appearing on leaves closer to the top. Should I give the Pineapple some calmag, mega crop, or mammoth p all of which I now have on hand? Also, I plan to replant today in a 3 gallon smart pot using promix organic and perlite but I’m not sure if I should do the first water with only ph 6.3 distilled water or if I should mix up nutes too. I’ll add some pictures in a few minutes of the lower leaves. Thanks for the reply’s guys.

it's not root rot. it's calcium deficiency, and hungry plants. they have enough leaves to be getting 250-300 ppm feed by now. in soil i would be giving them 300 ppm every third feeding by now.
and i may have misunderstood you, but it sounds like you ph corrected water, and are adding stuff to that water? no.....add stuff to the water, then ph correct, then give it a good 15-20 minutes, and check it again.

Yeh, water is the reason, absolutely agree. You probably need to add some fertilizer or some other components to water

Thanks guys. I always add everything to the water and then change the ph to 6.3 then let it rest and recheck again 15-20 later so at least I know now that I’m doing that part correct.

What are the brown spots from? Everything I’ve found says manganese or light burn and I’ve adjusted my light to 25-30k lux so that shouldn’t be the problem

it looks like advancing calcium deficiency to me. do the nutes you're using have more than one part? does one part say to add it first? if it does, are you?..
the reason i ask is that i use a two part "system" of dry nutes, which is just calcium nitrate and jack's 5-11-26.
you have to add the calcium nitrate first and let it all dissolve before you add the jack's, or the sulphur in the jack's and the calcium in the cal-nit will bond and precipitate out of your feed.

No it’s not a 2 part or 3 part system it’s just a single dry nutrient combo. I’ll send you a link of what I used. I did add in a tiny amount of the sweet candy too along with the tiny amount of mega crop using the seedling calculator on the Greenleaf site.

Mammoth p is expensive and I recommend just to use that in flower when needed. I suggest getting an all round microbe product. Yes replant if you want feed it dont wait with megacrop. I found that the calculator was too hot for what I wanted so do that at 1/4 strength or use a ppm meter and water it down to about the 250-300 range for that size plant. You can add the cal mag during just a watering later on.

When you transplant water in just water but feed it same day. You need to get the whole pot wet, you dont need nuted water to do that and waste it.
Stop worrying about the old leaves we are moving on from that.
Microbes very small amount once a week stop 2 weeks before chop
mega crop as needed
kelp once a week dont need alot stop at week 2 flower
humic acid once a week small amount stop 2-3 weeks before chop
any supplements as needed
done right at the right time and you shouldnt get a deficiency again.

When I start plants in Solo cups in Pro Mix I don't even think about giving them ferts until they are at least as big as yours. They will usually stay green on their own until that big. After that first feeding in the Solo cup they are ready to be up-potted. I think your roots aren't liking that soil yet. They may adapt but I would hope they have enough roots to be up-potted.

i don't like the ratio on megacrop. too much N. it's ok for veg, i think it's too much for flower. as far as i can figure out, my feed comes to 9-11-26 during veg, and 7-11-26 during flower. i only use a "booster" when i see them starting to swell, and then they only get it twice. after that, i start to drop ppm till they get down to about 400, and let them finish at that

Thanks everyone for your input! I ended up transplanting it into a 3 gallon pot yesterday and after removing it from the cup I immediately discovered the issue. The roots completely over took the cup and down at the bottom where I drilled drain holes roots spun around and around. When I pulled it out they dropped like a rolled up ribbon. I’m assuming every time I gave it water or the one time I fed it nutes everything ran directly down to the rolled up roots and either drowned them or burned them. I did end up feeding it a little bit of mega crop, recommend dose of calmag, and mammoth and used a half gallon of water. This was definitely not enough to saturate the whole pot but it was getting extremely late and I didn’t have time to mix up more water. Should I now use just regular ph correct water without anything else for the rest of the pot?

I did check on it earlier today and the yellow crispy leaves are turning back to green so that’s good. Anyways I’ll keep everyone updated as to what happens with the plant. Thanks again and have a great day.
