Nutrient toxicity or deficiency?

[420BongRips]

Look on my signature for my current grow and my most recent post as that's where I posted the pictures of the problem, but basically I am very experienced at growing and am knowledgeable but I'm a bit confused as I haven't experienced this problem I am having. My new plants are 3 weeks old. They are growing in solo cups and the pH of the soil is about between 6.5 and 7. I fed them cytoplus humic acid and seaweed concentrate at VERY little strength at about 1 1/2 weeks into my plants lives ( 1/10 , 1/15 strength) to give them a small boost. My plants have been starting to yellow or bleach from the bottom leaves and the new growth a little bit. One of the plants is growing deformed and weird, on the last picture you may see it with the plant that looks very indica like with broad leaves, the leaves are not symmetrical and the leaf growth is random and out of place. I'm not sure if they are starving for nutrients again or are just being burnt. You can see in one of the pictures of the spots on one of my plants, looks like scaly fish skin with black spots.

To long in a solo cup. Transplant them into a 3gal

That's funny I already had planned on transplanting them into 3 gallon pots tomorrow

Why do you say too long in solo cup? I've used solos for clones and seedlings to 10" tall and never had issues.

To OP. I'd up the micro and macros. Try nitrogen for a foilar spray until they catch up

What are those black spots? Can you brush them off?

i cant understand why people dont root there pots out before going up to the next size, if you put your small plants in large pots you will slow the growth, the wet dry cycle takes longer and if your using nitrate fertilizers you will get salt build up in the soil, patience will get you a big root ball which will give you fat buds

Yeah. Not sure how much effect it has but just wanted to know why @bbyb420 says too long in the solo

I could understand keeping it in a solo if u dont have the space but what is the point of keeping it in there after three weeks? I transplant after the roots fill the cup usually after the first 10 days. I should also mention that im an organic guy, and almost never use any bottled NPK products. Only thing I use that comes in a bottle is Hygrozyme and Earthjuice Grow for mother plants. Many different ways to grow dude if you wanna give nutrients to a solo cup go ahead but I say give those girls some fresh organic material to eat.

I would especially never use a heavy nitrate fertilizer for cannabis.
..If your roots dont fill up the cup within 14 days theres an issue causing slow growth...

No They don't come off.

Absolutely agree.
