Burning from over feeding............you are either feeding too much or too often.........or both.

Crispy Yellow Leaves Inflow EC=1333 w/ PH=5.8 vs Runoff EC=658 w/ PH=6.0. Insufficient nutes due to light intensity? Perhaps my PH meter is inaccurate? Light is 42 inches from canopy or ~600 PPFD. RH 65%, Temp 80 F.

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?

Burnt, should I throw it and start from zero?I have 1 burn auto for excessive light, should I throw this one and start from seed again or maybe flipping to 12/12?

Leaf yellowing Hi all. In the last 48 hours there has been a few lower leaves which have lightened in colour to a yellow. The whole leaf has changed at the same time so I’m not sure if this is an indication of an issue or if the leaves are being drained before the final ripening. Thanks 😊
