Hello People,
I need your help. I'm a totally beginner indoor grower. I've successfully germinated 10/10 BB Cheese Autos in rockwool. For two weeks I've used a 125W CFL Blue. Sadly I had some stretch. I'm using 15 L square pots with rockwool cubes+granulates for fill it up properly. I've putted the smaller cubes at the top of the pot.
I'm starting the 3rd week now and I've also started using my 600W DualSpectrum Sunmaster which is 1m above the plants.
That lamp is hot as hell but more or less I can keep the temp around 80F - 25-27 C. The water pH is 5.8 - 6.2
I've soaked the cubes in pH balanced water and I've also added some Formulex and a few drops of BioBuzz Root juice into it 1/4 - 1/8 rate.
I've also used a very little Formulex later for watering.
some of the plants are looking healthy and ok for me.
One of the plants has got yellow leafs which I've identified as Nitrogen deficiency. What do you think? I'm not sure..
The other one started to turning into yellow slowly but it has some wrinkling on the leaves as well! Any ideas? I couldn't id the problem accurately:
And the last one I think it is a nutrient burn but I would appreciate your confirmation please:
Thanks
Sig
