A shot of cal/mg would do her some good. It's also high in nitrogen.

Slow growth yellow leaf edges what to do?
Plant growing slowly (but still growing) with weak growth tips and yellow edges on leaves with interveinal chlorosis. Looks like overwatering / magnesium deficiency to me. I use a weighing scale to know when to water, but started the plant in 25L pot so this might have caused it.

The ph value is 6.3.👍 Yesterday I poured Short Flowering Powder "0.5g / 1.5l" in ph 6.28 water and today I notice these yellow spots. The beauty has grown 5 cm since yesterday.💪 What could that be? I'm just a bit worried?! 😲

Slow growth
I am noticing some yellowing has started on the new growth. Also they have been hardly growing over the last week. I did move the light up just a few days ago. Possible ph issues?

Two plants but one is small! Same tent, same nutrients and similar issues but different results
One of my plants is super small and I have no idea why. Initially I thought it was a magnesium deficiency but clearly it was not only that. The issues became apparent between weeks 4 and 6, right after the last transplant. Any idea what could've caused this?

Leaf issue
What seems to be the issue with older and new leaf growth here? It looks like cal-mag or potassium deficiency in my opinion, but I’m not really sure.

First week and never had little plants struggling so much to grow. Please, read my comment about the first week to a detailed explanation of the problem. The question is, what else can I do, except from waiting? I don't want to over do (again)

Magnesium deficiency?
It seems this girls is showing a magnesium deficiency? If this is correct, should I increase the cal-mag doses or should I just give her a high dose of epsom salt? Appreciate the help!

Deficiency or Burn?
I have used Happy Frog before with no issues. I am running my first 420 Fast Buds seeds and they seem to have nute burn for the last few weeks no matter what I do. Is this maybe a deficiency and not burn?

Yellow centre veins fan leaves
Yellowing of the inner vein of fan leaves only. Also sporadic yellowing and blemishes of whole fan leaves but only some, others fine nice and green. All bud leaves and buds don't appear affected. Is it just that she's nearing the end of her life cycle? Or over water/over nute?

Blue Dream Autos with Downturned Leaf Tips
23 days old. One started showing downturned leaf tips on new growth; others followed. Looks off-color, at least one is in early bloom. They’re in coco, 3-gal pots, 480W QB at 50cm, 2.2 EC daily, no pH check. Problems started after adjusting watering for larger plants. Any tips?
