poke_smotstarted grow question 4y ago

Hi grow bros. This is my first ever grow attempt with some AK-47 seeds. I am about 8 weeks in and have had to move plants indoors due to extreme heat here in Australia. Quite concerned at these marks on the fans that seem to be getting worse. Plants are inside now on 16-8 LS.

That is early sign of potassium deficiency since tips are straight. If they were curling up it would be nutrition burn.

Few of the older leaves have started going yellow with brown spots and shriveling up. I'm in week 7, week 3 of flower. I've been alternating nutes with Plain ph'd water, so only been adding nutes every 2nd water. Have now changed to every water. Is this just due to flowering? Ta

Is she worth it?What happened to this seedling? It sprouted with 2 cotyledons (looks like a piece is missing from one) but only one true leaf. It also sprouted with the leaves facing straight up but now they are all facing to the side. Is it worth keeping? It is on day 5 since soil germination.

Leaf discoloration There is a purple/blue tint to the tips of my older leaves. New growth coming in lighter green. Slightly red and purples stems only at base of oldest leaves. Leaves also taco curling slightly. Thinking phosphorous deficiency at this point, maybe combination N toxicity and heat?

Super thin leafs at the Top The leaves at the top are super thin, different to the others, the leaves are also darker green, I think it has some kind of problem! It looks like I overwatered it because the leaves are drooping, but that's not the case! Can anyone tell me what the problem could be?

Deep Ridges in leaves I have a whole strain (3 plants) exhibiting a general lack of vertical growth; but also deep veins and ridges causing eveb more malformed leaves. Same setup as my other 3 plants of another strain that are thriving. Looks like pH issue? Maybe this strain needs lower?

Hey, anyone got any idea or clue what's going on?I thought it was a manganese or iron deficiency from an early watering with high pH. Though I've fed/watered my other 2 plants pretty much the same stuff but she seems to be reacting really poorly. She seems to be getting better slowly.. I think. Thanks for taking the time. :)

The ladies are telling me something but I'm no weed-whisperer yet so I'm gonna need help. They are now 3 weeks since germination and I've only been watering them once a day with a spray. No nutrients yet. I have a 3-2-5 nutrient for Herbs & Tomatos but maybe only while flowering?

Droopy Leave Any reason to be worried? I have 7 plants going, 5 on the same feed. Only 2 plants are doing this but they are on different feeds. One has been mostly water and the other has been on the same feed as the rest but they are all fine.
