Concerned parent. Plants yellowing/clawing

im using happyfrog soil. Using big bloom only every other watering(grow big is on its way through the mail as I have a feeling my plants are nitrogen deficient.) guess I just need some help on pin pointing where the yellowing/clawing/shriveling is coming from. Most plants show same yellowing some worse than others. On some plants the only yellowing is happening right at the edges alone. Any help would be appreciated. Thanks!

That is not a N deficiency. The fark green and clawing is a sure sign of N toxicity. Also have you checked ph at all? Without some additional info id say nutrient overdose and some lockout. And cal/mag.

In that case I will cease using my nutrients until I'm sure the problem has been corrected. Thank goodness I didn't try to correct it with more nutes. You think just cutting back on the nutes will fix the problem or should the worst plants be flushed? Hell no wonder I'm on week 6 and they haven't sexed yet. Poor things are hurting.

I would give them plain water for the next 2-3 waterings then go 25% on nutes. This should straighten you out.

How often are you watering? Are you waiting for the first inch of soil to be dry? Also I would try to do nutrients every 3rd or 4th watering.
I would also make sure to PH your water and nutes mixes or else they won't be able to absorb the nutrients properly.

Here is a helpful video on watering your cannabis plants:

Also here's a video on how to properly PH your water:

Sound advice here and I agree totally ....usually good soil will buffer itself but I'm not to familiar with the soil your using ....but that dark green claw is N tox ....start a journal now so you know for next time ...I've written things down for 20 years for different strains on what works and what doesn't ....very helpful to look back on I suggest you start ....GL and listen to this guys advice

water ph matters very little in soil grow. Soil ph is what to focus on.

If you have nice water that is somewhat neutral sure, but you can really screw things up with the wrong PH.....

I would never tell anyone it doesnt matter...no matter what Medium.

SO sure for some folks that have their set up down and know their nutes and the effects on PH they would be able to let it slide more, but anyone else just starting and learning or doesn't have optimal set ups needs to pay attention what the water is like they are putting in to say otherwise...just makes no sense.

How about feed when they plants are hungry? This goes for watering too. I've never followed a "feed schedule". I let my plants tell me what they need. Also, I'd never advise new growers to put clones in pots that big.

Also, to the OP. FF nutes (like many others) have a tendency to lower the PH. What type of water are you using and do you pH the water accordingly?

What I said makes perfect sense when you understand that soil will buffer the shit out of water and pull the water ph to the soil ph in short order. Your water ph can be off a couple points and it won't matter if your soil has good ph. If your soil ph is off a couple points you're fucked, it doesn't matter what your water ph is.

Where did I say to ignore water ph? I spoke the truth. Soil ph is what matters most. Shame on you if you do not understand that.

Of course you should only water once the plants are hungry. By a feeding schedule I'm talking about using different mixes of nutrients during different stages of the plants life cycle so it is getting what it needs at the right time. I simply use water from the garden hose and yes I pH accordingly.

Why wouldn't you recommend transplanting into a pot of that size from clone?

"water ph matters very little in soil grow."

You should say water PH does not matter to me in MY soil grow.

Because not all soil and not all grows are the same.

I will say it again telling a new person this is just wrong.

with that I bid you farewell.

You can pH your water going in all you want but it will buffer to the mediums pH within an hour or less. What Bugeye said is correct.

eernt good way to kill your plants not checking the PH after adding Nutes.

My PH is 5 or less after bloom nutes/RO.....you really think I am going to toss that into my Medium?

No way and with that I bid you farewell as well.

i use good old rain water always have always will and never changed the ph never even used a ph test thingo have used many different soils from the cheapo potting mix or garden soil from the local hardware store to mixing my own from scratch i just always start in a good seed raising mix from hardware store to ensure a good root system in the beginning then transplant into whatever soil im gonna use with added perlite if needed as i test the soil with vegies before hand to be sure its well drained and such and have always have good results and just use seaweed solution and fish emulshion untill they show they are hungry then use an all purpose plant food usually use one designed for tomatos and such here are my 4 for this season still in the seed raising mix and have only been given 1/4 dose of seaweed solution once 20161205_070629.jpg

Don't let the door hit you on the way out. Go study up on buffering.
