What deficiency is this?

Getting no better had to bring inside due to bad weather worried about mold issue, under 600hps. Been flushed any ideas am going to get some cal-mag today.

Looking at the last pic, I'd say you're 4 weeks or better into flower, and the buds are sucking the life out of your leaves, because it's not getting enough N in it's diet..........

I've been growing for a few years and I've used all the expensive soils, made my own supersoil at one time, and IMHO Miracle Grow does the best for me. Whether I'm cloning or starting from bean. I transplant into fresh MG every time...from solo cup to 1 gal to 3 gal to 5 gal...Here's my worry/trouble free MG girl...notice the nice green leaves, she's 4-1/2 weeks into flower and only 90 days old, so far, and I haven't given her nutrients at all except for what's in the soil...

your plants are nearing the end of their life and they are sucking a;ll nutrients from the spots in the plants that really dont matter, they look fine.


and never use MiraclGro, lol.

WOW!! Look at the Miracle Grow Plant in the post before yours MG hater, bahaha...Man I'm fucking with you but really, don't tell people NOT to use a good product...AGAIN...Here's an MG girl 4-1/2 weeks in flower

Haha thanks so should I just up the N??

My first grow had that happen to 4 out of 8 plants, turned out to be
circle root and the plants stopped taking nutes in, I took a bamboo
stake and aerated the pot by poking the stake down to the bottom
of the pot all over, 3 days later presto!! everything turned green and
healthy. I don't know if this is your problem but they look just like mine
did. Aerating the roots never hurts and always helps.
After that grow I purchased root pouches for my girls.

I don't think it's calmag def. Looks like it's cannibalizing itself for N. That's not bad approaching harvest. I stop feeding 2 weeks before harvest (plain water only) to reduce the nutrients stored in the plant. They look rough, but smooth tasting.

BTW: I've never used MiracleGro, but it's not highly regarded by MJ growers. Not just the passionate organic anti-Scotts, anti-Monsanto crowd, but most synthetic growers too. Some people do well with it and remain with it. But, you might be able to do something better at that price point (price point usually being why people choose MG).

If/when you're interested in alternatives, take a look at Grow More Sea Grow (<<link). I bought two 5lb tubs and a 1.5lb container for $40 and that stuff will last 100-200. It's organic'ish. I've had a trouble with it acidifying the soil. I found feeding every other watering helped the acidity. I'm going to try weaker (1/2 tsp) every feeding and see how that works.

A lof ot MJ growers use Jack's Classic. Similar price as MG.

Could also have been an overabundence of magnesium which makes the soil sticky, and/or lack of calcium which keeps the soil fluffy. Aerating the soil is probably a good thing to do anyway. I've got an Control Wizard Accurate 8 soil PH probe. It's about 3/8" diameter. I worried it would damage roots. But, I find it helps through aeration.

Miracle Grow is good shit. I eat it for breakfast and I've never had a mag def in my life.
