BROWN SPOTS

[nugget505]

Hi, i have four plants in my grow space, 2 are 3 weeks old, the other 2 are 2 weeks old. one of the older ones has these brown spots on the leaves. I cut the bottom leaves off yesterday (the ones in the picture) as I thought this may rid the problem but some other leaves are now getting the same problem, this is the only plant in the space having this problem and I have no idea what it is... Any help please......
Also, one of the younger plants has a little yellow colour on the tips of 2 leaves and in the centre of the little bit of yellow there is a couple of red spots.......

check ph first (ALWAYS) but I wonder if you just need some fresh, ph corrected and prenuted soil and transplant. I like FFOF myself. Also check carefully for bugs and pests.

good luck

its a dose of heatstress. plants need some air circulation.

a fan.

it is currently in a coco/perlite mix, using canna nutrients and under 2 florescent lights. i have this set up in a cupboard which i leave open all day which is sitting near a window that i also leave open during the day to get fresh air into it...

if so you'll still need a fan blowing some air on to them gently.
