First Grow Blue Dream

You have an extremely alkaline substrate... try to transplant ASAP. It'll recover after that. If you leave in that pot, it'll take forever to correct pH and any imbalances to nutrients caused by crap coco. ( i feel your pain! ) it's whacky to be that high of a pH even with unprepared coco. The problem with unprepared coco is typicalyl Na+ content and/or what is bonded in the cation exchange sites (the stuff locked away from plants, unless equillibrium changes then it releases an overabundance of K+ as Ca and Mg ions have stronger affinities for the bonding sites). this is almost certainly pH related, as i've seen K-tox / Na-tox from crappy coco recently, lol. it'd be dark and sickly with twisted leaves and growing ugliy as hell.

If the coco has that pH, the best thing you can do is not waste any more time and put another one with well-prepared coco. While you're at those pH values, the plant won't be able to absorb nitrogen or iron, and not assimilating iron will also cause deficiencies in calcium and magnesium. Even if you water it with cal max, it's doomed to fail. The only solution I see is transplanting to a new substrate, but if it's been two weeks, it's better to start a new one because that's how long it will take to recover and get into a growth rhythm.

You are getting a combination of calcium deficiency and sulfur deficiency with the yellowing of the new leaves . As a coco grower myself . It would be best to buff your coco with calmag and iron supplement at a lower ph around 6.2 for better nutrient uptake . Sulfur will get locked out at a higher ph level. I recently had a problem with my ph pen giving wrong readings causing me to lock out my sulfur uptake . Hope that help and good luck to you ✌️🏾

Hi there! I think this is kinda up to your own preference but I took them off when I did the second topping and removed all the excess at one time to get all the stress to same day. You can remove them now if you want. Should not hurt that much imo

too much magnesium... could cause spots by locking out other stuff. that can cause the dark green lower foliage too.. can be other stuff.. See link i have in my profile comments for nute calculator -- type in %s from labels, and it spits out tabulated ppms for everything. follow instructions. it cna help you rule out what is possible. Also, a leaf symptome chart is linked from a diarty in my profile comments too.. just click the hypnotoad :P

Look like you might be having a nitrogen toxicity, Dark green leaves, shiny leaves, clawing, weak stems, and overall slow growth. Marijuana leaves that are nitrogen toxic often get “The Claw” or talon-like leaves that are bent at the ends. They also do an odd curving (or cupping) that is often mistaken for overwatering,

N is a possibility too -- didn't mean to type it that way :P the dots are something else, though.
