I'd reduce EC, especially nitrates.

New growth should be light green not dark green indicates a bit too much N to me.

Nute burn on leaf tips also

Overall though looking pretty good.

HELP!!!

clawing and browning of tips of upper levels, also leaves seem like shrunk or not fully stretched, I thought it was light problem so I decreased the intensity, and gave it Calcium nitrate and Magnesium sulphate nutrients once, after 1 day still no change, should I wait or could there be another problem? I don't know whats bothering her

[Yaboty]

just water

[Rootsruler]

Are you feeding them or just water?

[Yaboty]

Will do thanks for the advice

[Rootsruler]

Roots don't like light. Cover up the clear plastic pots.

HELP!!!! Lower Leaves are spotting then turning yellow and droppy, spraying and watering with hydrogen peroxide to kill fungus gnats didnt seem to fix it, im using ready mix soil mixed with perlite, 3 weeks old

Agree with Bluey and @Rwise.

Do a soil slurry test to find out what the soil pH is. This should give you an indication of if your pH is too low.

[Rwise]

IF you have these in soil the PH is low, PH for soil in veg is 6.2-6.5 and in flower (I see flowers) 6.5-6.8.

[Bluey]

Vary your pH intermittently. If growing in coco vary it 6 to 6.3. If in soil higher again. Read up on pH fir different mediums.

When in flower keep temps under 24⁰C.

Edit. I see in your earlier post (a bit over 3 weeks ago) you are growing in soil. I advised a pH of 6.4/5 then but you are giving it 6.0. Why? Your problem is too low pH.

Now I’ve got a nutrient deficiency for my autoflowers. Temps are between 20-30C one day it went to 37 but fixed that quickly. Feeding them pH 6.0 EC 1.2. Don’t know what the problem is so need some help

[Rootsruler]

Agreed. You just used too hot a fert for the baby roots. Water so that you get a good runoff, at least 20% - 30% like Bluey said.

I wouldn't use bat shit until the plant has established itself, well and truly.. It is one of the best natural fertilisers around but a bit much for seedlings.

You shouldn't be adding any nutes to that soil for at least 4 weeks, even though your only adding small amounts.

I'd give them a flush with plain water pH'ed to around 6.4/5. Let a bit run out the bottom and clean those excess nutes out. You seem to have a little bit if burn and nute deficiency caused by lockout from an excess.


Consider using larger pots next time.

Good luck
