Looking for some advice. I have noticed in the last week or two that my tomato plants have began to struggle. They started very well, nice thick stems, healthy foliage and the first setting of fruits was great, however the most recent growth is very spindly, flowers are dropping off without setting fruit and the plants seem to be going backwards.
I've been feeding them with Maxicrop weekly and they are set up on an automatic irrigation system and also in a greenhouse with autovents.
I am a KG on a private estate providing for a very busy kitchen and so any advice, pearls of wisdom or troubleshooting ideas would be greatly appreciated.
Thanks in advance
