I really need help. I am a new grower and have tried to research but getting more confused.
So info are as follows:
Medium: Coco 60% and perlite 40%
Age: 33 Days old from seed
Light: Luma 1200 Cob LED Grow Light (18/6 cycle)
PH Level: 5.6-5.9
Feed two days ago with following mix in a gallon :
Canna Coco A&B - 2.9mls each
Cannazym : 3.4mls
CMX Flairform (Calcium, Magnesium, Maganese, iron, zinc, copper, molybdenum and ) : 3.5mls
Regen A Root CX (Root regenerator) -3mls
Humudity: fluctuates between 40%-63% majority of time, however, lowest has been 38% and highest 99% (very short period 10mins)
Temperture: majority of time 21% - 26.5%
TALL/LST'D PLANTS- had noticed bottom leaves were yellowing and brown spots so took off plant. However, it is continuing and bottom part of plants are more yellow/light green. Newer leaves burnt tip/spots/tacoing up.
It started with tip burn about a week ago so flushed with PH watered @ 5.6 and then gave above mix three days after. I am unsure what strain, however, I have another strain (SHORTER PLANTS) which has had the same flush-feed as taller plants. These ones are no where like taller plants other than bottom leaves are yellowing.
I forgot to mention lights are hanging about 33inch away from plants. Light company recommends 32 inch for 550 ppfd. Which I think is a good ppfd for veg? Lol
[@marigoldhutchins] they look hungry to me. Up your feed to 5mL per gallon of A and B ✌🏻
@Admin BLG Thanks so much for the reply. I did think that it was a nitrogen deficiency at first. But as I continued researching it seemed like it was a potassium deficiency and a nitrogen toxicity (reason as top leaves are dark green, slightly folding in, tip burn and slight claw). If I up the A&B and keep everything else the same will it help prevent newer leaves from getting tip burn etc? Thanks again 😊
[@marigoldhutchins] everything else looks good to me. 👍🏼
Awesome, thanks so much ✌
