Nutrient deficiency?

Noelastarted grow question 6y ago

I noticed a whitish yellow spot on one fan leaf and a yellow tip on another at the beginning of this week. I have not fed any nutes yet just RO water, is this an early sign of nutrient deficiency?

Overfeeding protocols lol Overfed a couple hundred mls last feeding 2 days ago and the soil is still saturated. The plants leaves are wider and almost a neon green...it's not wilting or drooping. But for further reference on what to do in this situation. Thought I took a pic but I'm at work right now.

Help me Gods of education Hello boys and girls ✌️ Could someone help me on this green decoloration. I raised to 300ppm and the conditions stay the same as above. I just sprayed them with tap water (6.7pH) for like 3 days to raise some humidity. Could it be related? Could it be a lack of nutes?

Ora Her leaves started to get orange/brown spots a couple of weeks ago. Now all leaves go yellow and dry and die. Flushing her didn't help. Now I get similar symptoms on my Glue Gelato plant.

Hi, After I topped, the new growth tips started growing vigorously, but the leaves are weird. They have a loose&floppy appearance, the serrations on the edges are very wide and one of the leaflet didn't even grow 1/5th of the size of the others.. Do you know what it is? thanks!

Brown spots - can you tell what that is?Brow spots appeared on middle to top leaves (lower leaves are perfectly fine). I'm using a common soil "ready to use" from a gardening supply store + Earthworm Humus + some inert substrate, and didn't add any veg fert Can you tell me what it might be happening and how to fix it?

Plant growing weak (leaves); don't know what to do / to expect with her One of the plants I'm growing is looking feeble. Leaves are growing thin and she drinks less than the others. Same strain and same growing conditions. Seedling was stuck in his seed's hull and I had to remove it myself, scrunching a bit one of the cotyledons. What should I do ?

Can you take a photo at some photos Can someone take a look at the leaves and the photos and see if they are being overwatered or it’s a nutrient problem … The air pump was down for 6 hours back up and running But want to see if they are getting better . Photos online are 4 days apart … Are they getting better ?

Brown dots on leaves Getting some brown spots on leaves, thought maybe it was septoria so have been treating with neem oil. It’s still slightly spreading though, not on all leaves. Also a couple brownish/bronze patches. Any idea on what it could be?
