Its suposedly normal at week 7, but it might be lack of nitrogen, it may even be one of the reasons why it is so small.

Check your runoff pH. It should be between 6.3 and 6.5. If it's far off do a flush. Problem solved.

Having some discoloration on the fan leafs. From a quick Google it seems to be related to nitrogen deficiency. Would adding some coffee grounds or other organic matter quickly reverse this?

Can someone tell me what is this? I think the reason is that my nutrients are not balanced but I have no clue what deficiency this is, It could be so much easier to know the reason for this if I know what this is. pH pretty stable 5.8 Ec 1.5. Thanks!

Weak yellow leaves with red Stems
Weak yellow leaves on the bottom with red stems. I use 1/3 tap water, 2/3 filtered water for its pH levels. Could that be my issue? I feed twice a week Fox Farm Big bloom 2ml/l, Grow Big 2ml/l and Cal/Mag 0.5/l. Cal/Mag with every watering to make up for the soft water.

Day 40, I recently discovered my ph meter was faulty and my soil ph is high 7.3. I’m going to do a flush today with just water 6.5ph. I’m using living soil. What do you think will this be good for them? How do they look? My data shows me a daily average of 80.5F and 58% RH.

Seedlings going yellow
Could yellowing of leaves on seedlings be from too much fertilizer ( liquid fish, compost,seaweed type.) I wouldn't suspect iron deficiency as it is new premium potting mix that they are planted in. I did feed with about half strength liquid feet about 5 days ago.

Help please
Keep having issues with several of my autos on this grow & can’t figure out exactly what’s wrong! Watering at 6.3 to 6.5, feeding fox farm trio, 1 WW & 1 orange sherbet have not had any problems which is confusing me even more! Please check daily video for better idea! TIA!✌️🏼🌱

End of Flower, Yellow and crusty leaves ok ?
Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

Yellow lower leaves on 8-9 week old plants - Deficiency or age of plant?
Lower leaves are starting to yellow on some of the plants. I think I have corrected my cal/mag issues but now these yellow leaves. Going into week 9 of flower. Is this normal because of the age of the mature plant or a deficiency? Or is it still cal/mag deficiency?

45 days flowering yellowing
45 days of flowering, is it a bad yellowing or it's normal for this phase? Always did 1ml/L of biogrow, I think I'll put 2ml/L till flush. It's nitrogen, right?
