Everything at this point is ok. Plants are just starting to finish up and the leaves start failing. No worries at this point. Cheers

Heavy fast yellowing
I flushed my plant because of too high ppm reading from run off and now she seems to be going all yellow. Is this normal for this stage of the grow (all trichomes still white and small buds) or is this a definite nutrients deficiency during flowering?

Leaves turning yellow/red and burnt tips
This plant has been in flower for about 4-5ish weeks now. leaves are turning yellow and red with burnt tips. tested runoff pH at 6.8 today when I watered so I don't think its pH issues. been feeding a good bit of bloom nutes so ik its not P deficiency. Anything else?

Yellowing tips
Hi, I'm a newbie grower here. I have an autoflower that is nearly weeks old. I have started to notice some yellowing tips on the leaves. I have been feeding it some vitasol and pm13/14 as well as watering every two days. The growing medium is worm casing compost and perlite.

Slight yellowing/burnt tips and spots
Slight yellowing of leaf tips. Very little and plants are looking generally healthy. They are in bio bizz all mix! And theyve had one feed of fish mix and 2 of molasses I’m watering with rain water. Not too worried but would be good to know what is causing it

Nutrient burn or light damage?
Burnt tips appeared around week 3. I think the bio tabs are a bit too hot for this plant. The plant is growing at a good rate so I don't think a lockout is occurring. Burnt tips across most of top of plant. Could this be light damage? How to proceed or do I even need to worry?

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.
Is this a deficiency or some other kind of issue? Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.

Brown Tips on Leaves
I've noticed some brown tips starting to show on my autoflower plant -- the Auto Blue on my page. I personally believe it's from overwatering barely, though I have solid air circulation and try not to water until the soil is truly dry. Any help would be appreciated!

Too much light???
Do you guys think she is getting too much light? EC is no higher than before, but I’m starting to see yellowing of the tips... old and new leaves. It seems to me the leaves look somewhat anaemic in general. 100w LED was about 14”- 16”. Now its 19”.

Brown/burnt spots on 1 plant only
Hello, D49 (out of 70 theoritically) same strain, same nutes but only one plant looks affected (top right). Looks like it started 2 or 3 days ago. Could it be nute burns ou some kind of lockout? If yes should I flush or could i only give tap water for a few waterings?

Is this nute burn ? Appears after 4-6 days after watering , was watered with pH 6.5 but the run off seemed pretty acidic , the nutes added were bio bizz root juice at 1ml/l and bio grow at 0.5ml/l and they're about 3 weeks old
