White Russian plant. this yellowing is only occuring on the top couple levels of leaves of the tallest plant. it also, however, sits closest to where i add nutes. do you think its heat burn, or nute burn, or neither? Also notice how in pic one there is a tiny plant in the box: it's a moby dick plant started on the same date as the rest of the crop. Why didnt it grow? While researching i discovered it could be a potassium deficiency?
150 watt lght. Its on a pully system so its constantly at about 3 inchs from the tallest plant. ive noticed more burning edges on one of the other plants The last pic is of moby dick. its only about 1 1/2 inchs tall compared to the next smallest plant at about 4 inches..... PLEASEE HELP? any advice at all is immensely appreciated.
definitely lookin like heat burn on all the plants whats the temps? but idk second one kind look like underwatering but idk your using hydro so hows the roots look mayb something with the roots..
roots are looking fine temp was at 100.... got another fan now so hopefully they'll start looking better
